Fuel requirements
Octane rating: Volvo engines are designed for optimum performance on unleaded premium gasoline
with an octane rating AKI of 91, or above. AKI (ANTI KNOCK INDEX) is an average of the Research
Octane Number, RON, and the Motor Octane Number, MON. (RON + MON/2). The minimum octane
requirement is AKI 87 (RON 91).
Deposit control gasoline (detergent additives)
Volvo recommends the use of detergent gasoline to control engine deposits. Detergent gasoline is
effective in keeping injectors and intake valves clean. Consistent use of deposit control gasolines will
help ensure good driveability and fuel economy. If you are not sure whether the gasoline contains
deposit control additives, check with the service station operator.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. and Canadian
regulations require that pumps delivering unleaded gasoline be labelled "UNLEADED". Only these
pumps have nozzles which fit your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle
labelled "unleaded gasoline only". Leaded gasoline damages the three-way catalytic converter and the
heated oxygen sensor system. Repeated use of leaded gasoline will lessen the effectiveness of the
emission control system and could result in loss of emission warranty coverage. State and local vehicle
inspection programs will make detection of misfueling easier, possibly resulting in emission test failure
for misfueled vehicles.
NOTE: Some U.S. and Canadian gasolines contain an octane enhancing additive called methyl-
cyclopentadienyl manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System
performance may be affected, and the Check Engine light (malfunction indicator lamp) located on your
